A building inspector is checking a building height restriction. The code says maximum height is 20m. Standing 4.7 m from the building, he measures the angle of elevation of the top is 17 degrees Celsius. If his height is 167cm, is the height of the building legal?

Your class has covered the section(s) or chapter on angles of elevation and depression, so you're familiar with the basic terms and techniques (such as here). You've drawn the right triangle, using the given values for the along-the-ground distance x = 4.7m and the base angle A = 17 degrees (just "degrees", of course; whoever wrote this exercise accidentally gave the angle measure as a temperature!). You applied the appropriate trig ratio to solve for the height h of the top of the building above the inspector's head height. You then added the inspector's height (converted to meters, of course). And... then what?
Please be complete. Thank you!
